` To all whom 'it may Iconcern:

the cable guides.

Beit known that I, STEPHEN H. BLooMER, residing'at Seattle, in the county of King and State of Washington, have invented certain new' .and useful Improvements in Grading and Excavating Machines, of which the following is a specification.

My invention relates to certain new and useful improvements in grading and excavating apparatus, and more particularly has for its object to provide an improved apparatus of this character for moving earth, gravel, etc., from place 'to place, for leveling surfaces, filling flats, O'rading and ditching and the like, and whi il ap Maus will be 0f a simple and economicaif' construction and which will readily and effectively serve its intended purposes. Y A

My present invention, in its more subordinate nature involves certain improvements on the type of grading and excavating machine disclosed in my Patent $776,990, of December 6, 1904, and particularly has for its object to improve the construction of the cable driving mechanism, the corner cable supports and to provide means for supporting the cables between the corner supports so as to enable the cable to be raised or lowered or laterally adjusted as conditions may require.

With other objects in view which will be hereinafter -fully described, the invention also embodies certain novel detailsof construction, combination and arrangement of` parts all of which will be first described in detail, and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which z Figure 1, is a top plan diagrammatic view of. my apparatus. Fig. 2, is a perspective view of the corner cable Supporting means. Fig. 2, is a detail modified form of bearing suspension. Fig. 3, is a cross section on the line 3--3 of Fig. 1.

Fig. 17, is a similar view showing the same parts adjusted in another osition. Fig. 18, is a perspective view o the dumping mechanism, showing its cable supporting devices.

Referring `now to the accompanying drawings in which like letters and numerals of reference indicate like parts. in all of the figures, 1 designates the cable driving mechanism that imparts motion to the main cable' 20 that passes -around corner supports 30 and is adjustably supported between the corner supports 30 by transverse supporting cable and sheave mechanisms 40, as shown. 51 designates Scrapers connected to the cable 2O by supplemental secondary cables 50-50, as shown. .A dumping mechanism similar to that shown in my patent hereinbefore referred to, is also provided.

Referring now more partlcularly to Figs. 7 and `8, it-will be seen the cable driving mechanism comprises. a platform or truck 1a composed of I-beams mounted on wheels 2 that are fixedlyV secured to the front axles 3 and run loose on the rear axle 4, the rear axle 4 being connected with the truck 1 by a turn table or fifth-wheel mechanism 5,which is controlled through gears 5"*--6a and a hand Wheel 6b on a controlling shaft 6 so that by 4turning the hand wheel, the direction of movement of the truck 1 may be controlled. 7 designates a cross beam that is `sup orted asat 8.- 9 designates a main sheave sfiaft or spindle that is mounted in bearings 9a in the main frame of the truck and which carries a pair of spaced sheaves 9b and 9 res ectively that are flat on top and havey conical Webs 9UI beneath the sheaves being rovided with deep peripheral grooves 9* an having their lower peri heral edges provided with spaced notches Qf or a purpose hereinafter explained. The beam'7 is braced through turnbuckle and rod connections 10, as shown. In the forward end of the truck the driving and ower mechanism 70 hereinafter again referred to is mounted. Mounted in bearings 11 on the main frame of the machine is a second spindle 12 which is held at an angle to the horizontal while the spindle 9 is held vertically. The spindle 12 carries a sheave 12a of similar form to the sheaves 9b and 9c and is also provided with notches 9f, as shown. The endless cable 20 passes around the sheaves 9b, 12a and 9, as shown.

13 designates a winding platform Supported between the sheaves for the Scrapers -to pass upon in a manner similar to that vand through the elongated slot 13b whereby the inclined plate 14 can be arranged at any angle to the guideway 13, as desired. The

plate 14 is hingedly secured to the extension member 14a, as at14X, as shown.

In order to enable the small or supple mental cables 50 lto wind with the main cable 20, in the grooves of the sheaves 9b, 121?, 90,2 I provide guides 16, 17 and 18, the guides 17 and 18 being secured to the free ends of a cross bar'18"i that in turn is secured and carried by the beam 7 of the supporting frame,. friction rollers 18b being provided near the ends of the frame 18L to enter the grooves of the sheaves 9C and 12b, as indicated, so as to form not only guides for the arms, but also supports for the blocks thereof. The uide 18, it will be noticed, is of substantial y U- shape in cross section, and at its outer end terminates in a lip 180, for a purpose presently to be explained.

The guide 16 is of similar form to the guide 18, except that it is secured by bolts 16a toa bridge member 117 that has apertures 17a tocoperate with the bolts 16a, whereby the guide 16 can be adjusted along the bridge, member 117 to the desired position to allow for the main cable entering the groove of the sheave 9b at different points. The bridge member 117 is secured at 17b to the underside of the winding platform orguideway 13,' as clearly shown in Fig. 12, and the guide 16 is also provided with a lip 16C, similar to thev lip 18c of the guide 18, and lip 17 of thel guide 17.

By providing guides16, 17 and 18 and the peripheral slots in the sheaves, .the small cables 50 will befwound in the grooves of the l sheaves until the Scrapers 51 are close up to the sheaves when the small cable'50 will slip over the lips and fall into one of the eripheral notches 9f of the sheaves and t us the Scrapers will be carried around the axis off the shaft in a path of a radius substantially the same as that of the Sheave, and thus prevent the Scrapers becoming tangled up as theypass through the driving mechanism.

19 designates a main drive shaft which carries a shiftable pinion 19, that meshes .with a gearli)b on the spindle 9 and at the other endthe, shaft 19 carries a pinion 19' that meshes with a gear 19c on a countershaft 19d which is driven through the medium of gears 71e and 19f `from themain crank shaft 19gof the engine 70.

71 designates a supporting frame having bearings 1n which a drum shaft 71a is' journaled, and the drum shaft 71a carries a drum 7 1b which rotates loosely thereon, but may be held tov turn with the shaft 71l by a friction clutch 71c Shiftable into and out of engagement with the drum in any approved manner. Drum shaft 171a carries a .gear

Vwheel 71d which meshes with the shiftable pinion 71e4 on the crank shaft 19g, any suitable means -being provided for shifting the pinion 71e into and out of engagement with the gear 71d, such for vinstance as the or inary lever 71f, as shown.

72 designates a pinionnonvthe stub shaft 71k which meshes with a gear 73 on the front l axle 3 of' the truck So that the truck may be moved by means of its own power and when the truck is to be moved over bad roads., the friction clutch is shifted to bring the truck 1a into, locked engagement with the drum shaftand acable or anchor to pass around the v'drum and wind up thereon 'to aid in drawing the mechanism over roads in a manner similar to that disclosed in my patent hereinbefore referred to.

The engine 7 0 is fed from a boiler 70 and 'any suitable controlling valve mechanism .mounted, the sheave 30" having its s i'ndle 30I mounted in a bearing 3l'a of a brac et31 which ispivotally secured 'by an eye bolt 32 to the postV 30. l v

31"y Idesignates an eye carried byv the bracket 31 to which a block 33 is secured, a

.second block being securedy tothe eye bolt 35 on the upper end of the post 30' anda cable34apasses over the blocks 33-34 kso thatv thek bracket 31 can be adjustably held in position.- kThe Sheave 3.()f is grooved tol receive the main cable 20 which.` passes around the same.

36 designatesa winding drumwhich is carried by the corner supportin means and on which a guy cablek 36a is a apted to be Wound, the lcable 36a passes through a sheave Sb on the` platform 3U and through a block 37 anchored to the ground-fat a definite point and through a second-f block 38 secured to the supporting post 30" by a hook andeye bolt 38, as shown. A second winding drum.36x'coperates with a second cable 36Y and sheave 36Z and blocks 38x aud BSY are similarly secured by anchors to the ground and by eye bolts to the post 30, the first guy cables 36?' being held to exert fcnsion at right angles 'to the second set, as Shown.' The bracket 31 may be adjustably heldl by rods and turn buckles 75, as shown,

in detail in Fig. 2, in place of the blocks 335-34 and the cable which passes thereover..

- By reference to Figs. 1 and 3, it will be seen that in order to su port the main cables 2() at definite. heights rom the ground between the corner supportsl and also to enable the cables to be shifted from side to side as shown in dotted lines in Fig. 1, I mount a pair of tripods at each side ,of the main portion of the apparatus, as shown, and these tripods are designated by the reference numerals .4m-40h. The tripod 40a is anchored to a post or deadman and carries a sheave 4()x around which the endless cable 41 passes. The endless cable 41- passes over a double sheave 4()y on the other tripod 40b and winds around the gypsy drum, whereby the endless cable 4l may be shifted to a greater or less degree as may be found desirable. The sled 42 carries a winch or winding drum 42 around which an anchor cable 42 is adapted to be wound, the other ends of the anchor cable 42b being anchored to a post or deadman in the ground, asl

showl 43 r eslgnates a three sheave block whlch is held over the main cable 20 by means of aV double tackle 44 provided with a hook 44" to hook into an eye bolt 43LL of the sheave 43 and a sw`vel member 44b to permit passage of the endless cable 41, which serves to support the sheave block 43. The she'ave block 43 is made of boiler iron bent unto substantial U- shape in cross section, the upper and lower portions 43" and 43 being spaced art by collars 43 and bolts 43e asishown. encath the lower plate 43 the grooved sheaves 43f are mounted and the sheaves k43f are close enough together to prevent the main cable 20 slipping out but spaced sufficiently apart Any number,

block 43 is also supported by a double tackle 44 from a cross beam 60 of the dumping mechanism (50 so as to support the main cable 2() at this point.

In Fig. 14, I have shown a detailed er spective view of a hook which isI carried) by the small or supplemental cables 50 and is adapted to hook into the bail 51X of the scrapers 51 and thehook is designated by the reference numeral 52 and includes a groove 52a and a circular portion 52b in which the supplemental cable 50 is held. This portion 52b is adapted to ride in the grooves of the sheaves as the small cables pass there around and these aid in holding the small cables in the grooves in the sheaves, and in order to minimize wear in the small grooves they may be provided with a series of metallicwashers 13, as shown in Fig. 14.

So far as described, the manner in which my invention Operates will be best described as follows: The course of ground to be operated upon is 'first determined by a suitable survey or otherwise and the cable driving mei' hanism moved into a position at the most suitable point. AThe corner su )ports are then placed in proper position and securelyanchored, afterwhichthe cable 20 is strung and the plows or sera ers attached to the cable. The supplementa cables 50 and transverse supporting mechanism 40 are also placed in position and the cables pass through the sheares thereof. Should the cable not lie directly over the course to be operated upon, the saine may be moved to the desired point by the transversev cable and adjusting and support ing mechanism 40, as before described. The drive mechanism is generally placed at the point where the earth is to be removed. The scraper dumping mechanism G0 is placed at the point where the carthis to bedeposited. Upon the cable drive mechanism being set in motion the scrapers are moved forward by the cable and are filled with earth, dirt or gravel. They are then carried forward to the dumping mechanism, which, operating in the manner before described, in my patent hereinbefore referred to, will cause one of the scraiers to dump their load at the place desire( .r ln dum )ing the srrapers are u set and may be rgfited by a suitable atten( ant before theycan reach the driving mechanisln. After the Scrapers have been dumped they pass on forward and are carried around the end support sand back to the driving mechanism. As they arrive at the drive mechanism they will pass up the inclined entrance to the platform and be carried around the spindles in the drive mechanism and pass upwardly i down the next incline, where they will be again carried to the place where they again become filled with earth.

From the foregoing description, taken in connection with the accom anying drawings, it is thought the comp ete construction,

-' stantially as shown and described.
